I would caveat any discussion about licensing with "it all depends". I have been at several sites over the last 8 years or so and I know of no two companies that paid the same thing. It all depends on how well you negotiate with your "used car" salesman (and how close to EoQ you are :) ) some sites paid exponentially less than others on certain features like RAC.

I would encourage ANYONE doing negotiations to force Oracle into including ALL of the management packs as you cannot disable nor can you   NOT install them - especially 10g+... (in my book, that is like the old trick where the book publishers would send you a book, and then hound you until you paid for it and if you didn't want it you could return it. The laws in most states state that if you receive something you did not order, not only do you not have to pay for it, you also don't have to return it and IMO, software is no different - especially if I cannot not install it, uninstall it or disable it.

Laws in your state/country may vary. Received on Thu Feb 26 2009 - 19:29:07 CST
